Measurement solutions for Distance

How to choose a displacement technology

Displacement is the most crowded category in measurement, and the right sensor is decided by the target material and the environment far more than by accuracy. This is how the five technologies we supply really differ, and where each of them stops working.

Applications

  • 3D component scan before laser cladding

    With laser cladding, the component surface is melted by a laser beam and joined to form a new, pore-free layer by the addition of a powdered filler material. Prior to laser processing, the components are scanned with a scanCONTROL laser…

Frequently asked questions

Answers to the most common questions about our products and services

Usually five to ten working days from when your samples reach our lab. You get a written report with the measured results and a recommended configuration.

Both. We can supply the instrument alone, or install, align, configure and prove it on your line with a measurement capability test before handover.
